| Abstrakt: | Background: Prematurity is a major public health problem and it's associated with a high mortality and morbidity. In Tunisia, few investigations studied this area. Aim: To determine the rate and the risk factors of in-hospital mortality of very preterm infants. Methods: We conducted a retrospective monocentric study. We included all premature Infants born at less than 326 weeks of gestation (< 33 Weeks) without major congenital anomalies admitted from January 2011 to December 2012 in the neonatal intensive care unit (NICU) of Charles Nicolle Hospital (Tunis-Tunisia). To determine in-hospital mortality related risk factors, we created and compared two groups: group of "Survivors" until discharge from our hospital and group of "Dead" before discharge. Multivariable logistic regression models were used to assess the association between risk factors and in-hospital mortality. P-value < 0.05 was considered statistically significant. Results: During the study period, 7606 livebirths (LB) were recorded; among them 113 were very premature infants. The prevalence of high prematurity was 1,4 % LB. Very premature infants were divided in 24 extremely preterm infant (13%) and 89 moderately preterm infants (87%). Mean weight at admission was 1338g (±349g) and the mean gestational age was 30 weeks (±1,7). The mean hospital stay was 26 days (±17days) with an average weight at discharge of 1942g (±249). Neonatal morbidity was mainly caused by respiratory distress (42%), early neonatal anemia (64%), intraventricular hemorrhagea (15%), associated-care health infection (37,6%). In hospital mortality rate was 32 %. Mortality risk factors identified through multivariate analysis were: extreme premature infant (p<0,05), extremely low birth weight (p<0,01) and circulatory disorders (p<0,05). Conclusion: Very preterm infant represented 1,4 % of all live births. The mortality rate of very premature infant is still high and mainly associated to neonatal respiratory distress. Improving prevention and neonatal management still very required. |
